Investigating community-based care service factors delaying residential care home admission of community dwelling older adults and cost consequence. Age Ageing 2023; 52:afad195. [PMID: 37890521 PMCID: PMC10611449 DOI: 10.1093/ageing/afad195] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Revised: 08/04/2023] [Indexed: 10/29/2023] Open
Abstract
OBJECTIVES To examine factors contributing to delaying care home admission; and compare the rates of care home admission and cost consequence between two government subsidised programmes, Veterans' Affairs Community Nursing (VCN) and Home Care Package (HCP). METHODS Our national, population-based retrospective cohort study and cost analysis used existing, de-identified veterans' claims databases (2010-19) and the Registry of Senior Australians Historical Cohort (2010-17), plus aggregate programme expenditure data. This involved 21,636 VCN clients (20,980 aged 65-100 years), and an age- and sex-matched HCP cohort (N = 20,980). RESULTS Service factors associated with lower risk of care home admission in the VCN cohort were periodic (versus continuous) service delivery (HR 0.27 [95%CI, 0.24-0.31] for ≤18 months; HR 0.89 [95%CI, 0.84-0.95] for >18 months), and majority care delivered by registered nurses (versus personal care workers) (HR 0.86 [95%CI, 0.75-0.99] for ≤18 months; HR 0.91 [95%CI, 0.85-0.98] for >18 months). In the matched cohorts, the time to care home admission for VCN clients (median 28 months, IQR 14-42) was higher than for HCP clients (14, IQR 6-27). Within 5 years of service access, 57.6% (95%CI, 56.9-58.4) of HCP clients and 26.6% (95%CI, 26.0-27.2) of VCN clients had care home admission. The estimated cost saving for VCN recipients compared to HCP recipients over 5 years for relevant government providers was over A$1 billion. CONCLUSIONS Compared to an HCP model, individuals receiving VCN services remained at home longer, with potentially significant cost savings. This new understanding suggests timely opportunity for many countries' efforts to enhance community-based care services.

Abstract
ObjectivesTo: (1) outline the research produced using linked data from the Registry of Senior Australians (ROSA) which informed the recommendations from Australia’s Royal Commission into Aged Care Quality and Safety (delivered February 2021); (2) describe the Australian Government Aged Care Roadmap Reforms (announced May 2021) resulting from the recommendations.
ApproachROSA was established in 2017 and is led by a partnership of scientists, clinicians, aged care providers and consumer advocates from nine organisations seeking to improve the lives of Australians in aged care. ROSA is a Clinical Quality Registry comprised of linked national and cross-jurisdictional aged and health care data and includes a national historical de-identified cohort (3.5 million individuals, 2002-2020) and a prospectively enrolled cohort in the state of South Australia (26,600 individuals, 2018-current). This is a summary of ROSA’s high-quality evidence used by the Royal Commission and translation of this evidence into policy by leveraging existing data infrastructure.
ResultsBetween 2019-2020 the ROSA team led the delivery of four in-depth reports for the Royal Commission, contributed data and expertise to an additional four published Commission reports. Examples of ROSA outputs informing the Commissions’ recommendations included: evidence of national increased psychotropic medication use following entry to residential aged care, evidence of higher risk of mortality and entry to permanent care while waiting for home care packages, development of quality indicators to monitor quality and safety of care nationally, and to facilitate international comparisons and benchmarking. Examples of recommendations included in the Australian Government Aged Care Roadmap: release of substantial funding to increase the availability of home care packages, public reporting system for quality and safety monitoring and several changes to medication management.
ConclusionRegistries are key resources for high quality real-world evidence generation needed to inform national investigations, ultimately leading to significant sector reform. The ROSA experience highlights that cross-sectoral data linkages, together with technical expertise, informed by clinicians and consumers, are invaluable resources for system reform and policy generation.

Stakeholders' perspectives of mobile x-ray services in support of healthcare-in-place in residential aged care facilities: a qualitative study. BMC Geriatr 2022; 22:700. [PMID: 35999503 PMCID: PMC9400207 DOI: 10.1186/s12877-022-03162-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2022] [Accepted: 05/19/2022] [Indexed: 11/10/2022] Open
Abstract
Background There is interest in reducing avoidable emergency department presentations from residential aged care facilities (RACF). Mobile x-ray services may enable the delivery of healthcare in residential aged care facilities. Accordingly, the Australian Government in November 2019 introduced a Medicare Benefit Schedule rebate providing for a ‘call-out’ fee payable to radiology service providers. This study aims to understand stakeholder perspectives on the benefits of mobile x-ray services and the factors influencing their adoption by RACFs. Design, setting, participants Twenty-two semi-structured interviews were conducted between October 2020 and February 2021 with a range of stakeholders involved in healthcare delivery to residents: a) general practitioners; b) emergency department clinicians; c) paramedic clinicians; d) a hospital avoidance clinician; e) radiology clinicians and managers; and f) aged care clinicians and managers. Thematic analysis was conducted. Results Mobile x-ray services were considered valuable for RACF residents. Lack of timely general practitioner in-person assessment and referral, as well as staffing deficits in residential aged care facilities, reduces optimal use of mobile x-ray services and results in potentially unnecessary hospital transfers. Conclusions The use of mobile x-ray services, as a hospital avoidance strategy, depends on the capacity of RACFs to provide more complex healthcare-in-place. However, this requires greater access to general practitioners for in-person assessment and referral, adequate staffing numbers and appropriately skilled nursing staff within residential aged care facilities.

Abstract
Background: Studies related to clinical quality indicators (CQIs) in dementia have focused on hospitalizations, medication management, and safety. Less attention has been paid to indicators related to primary and secondary care. Objective: To evaluate the incidence of primary and secondary care CQIs for Australians with dementia using government-subsidized aged care. The examined CQIs were: comprehensive medication reviews, 75+ health assessments, comprehensive geriatric assessments, chronic disease management plans, general practitioner (GP) mental health treatment plans, and psychiatrist attendances. Methods: Retrospective cohort study (2011–2016) of 255,458 individuals. National trend analyses estimated incidence rates and 95% confidence intervals (CI) using Poisson or negative binomial regression. Associations were assessed using backward stepwise multivariate Poisson or negative binomial regression model, as appropriate. Funnel plots examined geographic and PRAC facility variation. Results: CQI incidence increased in all CQIs but medication reviews. For the overall cohort, 75+ health assessments increased from 1.07/1000 person-days to 1.16/1000 person-days (adjusted incidence rate ratio (aIRR) = 1.03, 95% CI 1.02–1.03).Comprehensive geriatric assessments increased from 0.24 to 0.37/1000 person-days (aIRR = 1.12, 95% CI 1.10–1.14). GP mental health treatment plans increased from 1.30 to 2.1/1000 person-days (aIRR = 1.13, 95% CI 1.12–1.15). Psychiatric attendances increased from 0.09 to 0.11/1000 person-days (aIRR = 1.05, 95% CI 1.03–1.07). Being female, older, having fewer comorbidities, and living outside a major city were associated with lower likelihood of using the services. Large geographical and facility variation was observed (0–92%). Conclusion: Better use of primary and secondary care services to address needs of individuals with dementia is urgently needed.

Residents' perspectives of mobile X-ray services in support of healthcare-in-place in residential aged care facilities: a qualitative study. BMC Geriatr 2022; 22:525. [PMID: 35752763 PMCID: PMC9233760 DOI: 10.1186/s12877-022-03212-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Accepted: 05/31/2022] [Indexed: 11/30/2022] Open
Abstract
Background Mobile X-ray services (MXS) could be used to investigate clinical issues in aged care residents within familiar surroundings, reducing transfers to and from emergency departments and enabling healthcare to be delivered in residential aged care facilities. There is however little research exploring consumer perspectives about such services. The objective of this research was to explore the perspectives and preferences of residents about the provision of MXS in residential aged care facilities, including their knowledge about the service, perceived benefits, and factors that require consideration for effective implementation. Methods A qualitative study design was used. The setting for the study included four residential aged care facilities of different sizes from different parts of a South Australian city. Purposive sampling was used to recruit participants. 16 residents participated in semi-structured interviews that were audio-recorded and transcribed verbatim. Data were inductively derived using thematic analysis. Results Participants had a mean age of 85 years, 56% were female, 25% had dementia and 25% had had a mobile X-ray in the last 12 months. Four themes were developed. Participants preferred mobile X-rays, provided as healthcare-in-place, to improve accessibility to them and minimize physical and psychological discomfort. Participants had expectations about the processes for receiving mobile X-rays. Costs of X-rays to people, family and society were a consideration. Decision making required residents be informed about mobile X-rays. Conclusions Residents have positive views of MXS as they can receive healthcare-in-place, with familiar people and surroundings. They emphasised that MXS delivered in residential aged care facilities need to be of equivalent quality to those found in other settings. Increased awareness of mobile X-ray services is required.

A vulnerable residential environment is associated with higher risk of mortality and early transition to permanent residential aged care for community dwelling older South Australians. Age Ageing 2022; 51:6540139. [PMID: 35231094 PMCID: PMC8887847 DOI: 10.1093/ageing/afac029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Indexed: 12/02/2022] Open
Abstract
Objectives This study examined the impact of the residential environment, measured by the Healthy Ageing/Vulnerable ENvironment (HAVEN) Index, on risk of mortality or entry into Permanent Residential Aged Care (PRAC). Design A retrospective cohort study using data from the Registry of Senior Australians (ROSA) was conducted. HAVEN Index values were matched to the ROSA by residential postcode. Study setting and Participants Older individuals living in metropolitan Adelaide and receiving their first eligibility assessment for aged care services between 2014 and 2016 (N = 16,944). Main Outcome Measure Time to death and entry into PRAC were the main outcomes. Results A higher HAVEN Index value, which represents a favourable residential environment, was associated with a lower risk of mortality and delayed entry to PRAC. For every 0.1 unit increase in HAVEN Index value, the risk of mortality is 3% lower (adjusted hazard ratio [HR], 95% confidence interval [CI] = 0.97, 0.96–0.99) and the risk of entry to PRAC is 5% lower (adjusted subdistribution HR, 95%CI = 0.95, 0.94–0.97) in the first 2 years following aged care assessment. After 2 years, the HAVEN Index was not associated with the risk of transition to PRAC. Conclusion Place-based health inequalities were identified in Australians seeking aged care services, demonstrating that a better understanding of local neighbourhoods may provide insight into addressing ageing inequalities. Spatial indexes, such as the HAVEN Index, are useful tools to identify areas where populations are more vulnerable to adverse health outcomes, informing responses to prioritise local improvements and health interventions to enable healthy ageing.

Abstract
PURPOSE Clinical quality registries (CQRs) are being established in many countries to monitor, benchmark, and report on the quality of dementia care over time. Case ascertainment can be challenging given that diagnosis occurs in a variety of settings. The Registry of Senior Australians (ROSA) includes a large cohort of people with dementia from all Australian states and territories identified using routinely collected aged care assessment data. In ROSA, assessment data are linked to information about aged and health service use, medicine dispensing, hospitalisations and the National Death Index. The ROSA dementia cohort was established to capture people for the Australian dementia CQR currently in development who may not be identified elsewhere. PARTICIPANTS There were 373 695 people with dementia identified in aged care assessments from 2008 to 2016. Cross-sectional analysis from the time of cohort entry (e.g. when first identified with dementia on an aged care assessment) indicates that individuals were 84.1 years old on average, and 63.1% were female. More than 44% were first identified at entry to permanent residential aged care. The cohort recorded more severe cognitive impairment at entry than other international dementia registries. FINDINGS TO DATE The cohort has so far been used to demonstrate a declining prevalence of dementia in individuals entering the aged care sector, examine trends in psychotropic medicine prescribing, and to examine the impact of dementia on aged care service use and outcomes. FUTURE PLANS The ROSA dementia cohort will be updated periodically and is a powerful resource both on its own and as a contributor to the Australian dementia CQR. Integration of the ROSA dementia cohort with the dementia CQR will ensure that people with dementia using aged care services can benefit from the ongoing monitoring and benchmarking of care that a registry can provide.

Abstract
IntroductionInfection is a major complication following joint replacement (JR) surgery. However, little data exist on baseline use of antibiotics following primary JR and how use changes with subsequent revision surgery.
Objectives & ApproachOur study objectives were to describe community use of antibiotics before and after primary total hip replacement (THR) and change in use pre and post revision procedure.
Registry data were linked with national medication dispensing data using probabilistic record linkage. Patients with THR for osteoarthritis in a private hospital between 1999 and 2017 were included. Three groups were analysed: patients with primary procedures revised for infection, revised for non-infection reasons and those not revised. Rate of antibiotic dispensing/month was calculated as number of patients dispensed at least one antibiotic in a given month divided by number of patients at-risk.
ResultsThere were 102,577 patients included in the non-revised group, 3,156 revised for non-infection and 520 revised for infection. Prior to primary THR, baseline antibiotic dispensing rate was 9-11%/month in all groups. Post-primary rates were similar (10-11%) for non-revised and revised non-infection patients but higher (16-17%) for revised-infection patients. In 1, 6 and 12 months preceding revision for infection, antibiotic use was 55%, 27% and 22%, respectively. For patients revised for non-infection, antibiotic use was 21%, 14%, 13%, respectively. One-month following revision for infection, 82% of patients were dispensed antibiotics, remaining high (38%) at 6-months and 28% at 12-months. In the revision non-infection group, antibiotic use was 48% first month post-surgery, reducing rapidly to 15% at 6-months.
Conclusion / ImplicationsNon-revision and revision non-infection patients had similar antibiotic dispensing before and after surgery. Revision infection patients however, maintained higher antibiotic dispensing post-primary, pre and post revision. This may reflect either ongoing infection, need for long-term suppressive therapy or reluctance of treating physicians to terminate treatment.

Abstract
IntroductionMonitoring of joint replacement (JR) data from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) has reduced revision rates and improved surgical practice. Outcome assessment post-arthroplasty is limited however, to revision (reoperation) surgery and mortality outcomes. The AOANJRR National Data Linkage project seeks to broaden the scope of outcomes investigation in Australia by linking registry and health administrative datasets.
Objectives and ApproachUsing linked registry and administrative data, the project seeks to describe and quantify national/regional trends and variation in major complications (infection, dislocation, arthrofibrosis, chronic pain, venous thromboembolism, cardiac events), malignancy and health service utilisation (readmissions, emergency encounters and inpatient rehabilitation) following hip, knee and shoulder joint replacement surgery. Evidence will be generated on how these outcomes are associated with and vary according to patient, surgical, implant, hospital and pharmacological factors.
As Australia lacks a national identifier, seven linkage agencies are probabilistically linking AOANJRR hip, knee and shoulder replacement data (1999-2017) with 20 datasets. Datasets include government-subsidised health services, procedural and prescription data. Hospital separations and emergency attendance data from Australia’s eight jurisdictions together with national cancer registry and rehabilitation service data are also planned for linkage. Linked data are maintained in a secure remote access computing environment.
ResultsTo date, national Medicare Benefits Schedule, Pharmaceutical Benefits Scheme and the Australian Cancer Database data have been linked with >900,000 AOANJRR patients, representing 607.6 million health service records (1999-2018), 467.7 million prescriptions (2002-2018) and 184,000 cancer records, respectively. Remaining linked data will be available in mid-2020. Some initial summary results across a selected range of studies will be presented.
Conclusion / ImplicationsThis national data-linkage program will identify areas for improvement in joint replacement surgery and modifiable risk factors contributing to poor patient outcomes.

Profile and Trends in Comorbidity for Patients Undergoing Hip and Knee Arthroplasty Using the Rx-Risk Measure with Pharmaceutical Dispensing Records. Int J Popul Data Sci 2020.

Abstract
IntroductionPatient comobidity at time of primary joint replacement (JR) impacts on outcomes including revision and mortality. Understanding changes in comorbidity profiles is important when assessing change in outcomes over time. Most arthroplasty registries have limited comorbidity information due to their minimum dataset. One approach to obtaining additional comorbidity data is linking registry data with national administrative data.
Objectives and ApproachObjectives were to quantify pre-operative comorbidity profile of patients undergoing primary total hip replacement (THR) and total knee replacement (TKR) for osteoarthritis. Also, to examine temporal trends in individual comorbidities for THR and TKR patients.
National pharmaceutical dispensing data were linked with THR and TKR arthroplasty patients. Medication dispensing histories in 12-months preceding JR (2003-2017) for 237,333 THR and 394,965 TKR patients, were mapped to 47 comorbidity classes using the Rx-Risk-V measure - a pharmacy-based measure of comorbidity. Comorbidity scores were calculated by summing comorbidity categories for individual patients. Trends in comorbidity scores/categories were described, with comorbidity information presented by PBS beneficiary category (concessional/general), stratified by age (<65/≥65 years).
ResultsMedian (interquartile range) comorbidity scores were higher in concessional patients ≥65y, THR:5(3-6), TKR:5(3-7); <65y,TKR:5(3-6) but not THR:4(2-6). Comparative scores for general patients (both ages) were THR:4(2-6) and TKR:3(2-5). Trends in median comorbidity scores were consistent across study period, THR:4- 5(concessional)/2-3(general) and TKR:4-5(concessional)/4(general). Commonly identified comorbidities in younger concessional THR patients were pain, measured by opioid use (62.4%), inflammation/pain, measured by use of non-steroidal anti-inflammatories (62.2%), GORD (36.2%) and hypertension (36.1%). Individual comorbidities remained generally stable over time. However, increased patient proportions were seen in THR concessionals <65y for opioid pain (59.1%-71.1%), depression (24.5-42.5%), whilst inflammation/pain (82.1-56.1%) and antiplatelet use (≥65y:23.5-9.2%) declined.
Conclusion / Implicationsn THR or TKR patients no appreciable change in comorbidity score or comorbidity profile occurred over time. This suggests that improving JR outcomes over time are unlikely due solely to variation in patient comorbidity profiles.

Abstract
BACKGROUND AND PURPOSE There are limited population-based data on utilization, outcomes, and trends in total knee arthroplasty (TKA). The purpose of this study was to examine TKA utilization and short-term outcomes in a pre-paid health maintenance organization (HMO), and to determine whether rates and revision burden changed over time. We also studied whether this population is representative of the general population in California and in the United States. METHODS Using hospital utilization and membership databases from 1995 through 2004, we calculated incidence rates (IRs) of primary and revision TKA for every 10,000 health plan members. The demographics of the HMO population were compared to published census data from California and the United States. RESULTS The age and sex distributions of the study population were similar to those of the general population in California and the United States. 15,943 primary TKAs and 1,137 revision TKAs were performed during the 10-year period. Patients below the age of 65 accounted for one-third of all primary replacements and one-third of all revision replacements. IRs of primary TKAs increased from 6.3 per 10,000 in 1995 to 11.0 per 10,000 in 2004, at a rate of 5% per year (p<0.001). IRs of revision TKAs increased from 0.41 per 10,000 in 1995 to 0.74 per 10,000 in 2004 (p=0.4). Revision burden remained stable over the 10-year observation period. Surgical complications were higher in revision TKA than in primary TKA (10% vs. 7.7%; p=0.007). 90 day complication rates for primary and revision TKA including death were 0.3% and 0.6% (p=0.1) and for pulmonary embolism 0.5% and 0.4% (p=0.6). 90 day re-admission rates for primary and revision TKA including infection were 0.5% and 4.2% (p<0.001), for myocardial infarction 0.1% each, and for pneumonia 0.2% and 0.4% (p=0.08). INTERPRETATION The incidence of primary and revision TKA increased between 1995 and 2005. The rates of postoperative complications were low. Comparisons of the study population and the underlying general populations of interest indicate that this population can be used to predict the incidences and outcomes of TKA in the general population of California and of the United States as a whole.

Abstract
The Kaiser Permanente National Total Joint Replacement Registry (TJRR) is a national level database designed as a postmarket surveillance system for elective total hip and knee replacement. As of March 31, 2007, the TJRR recorded 16,945 primary total hip arthroplasties (THA), 2144 revisions (11.2%); and 30,815 total knee arthroplasties (TKA), 1794 revisions (5.5%). Statistically significant findings include: older age and higher American Society of Anesthesiology risk scores for revision THAs. Osteoarthritis is the most common diagnosis for THA and TKA, and aseptic loosening and instability are most common in revision THAs and TKAs. The TJRR has provided a mechanism for recalls, identified patients at risk for early revisions and changed practice by providing feedback to physicians.

Abstract
Manipulations have been considered effective only in the early postoperative period. From a total joint registry containing 9640 primary total knee arthroplasties (TKAs), 195 patients who underwent manipulation under anesthesia (MUA) were identified. A total of 102 had MUA within 90 days (early), and 93 more than 90 days (late) after TKA. Average pain (10-point scale), satisfaction (10-point scale), flexion (degrees), and extension (degrees) were recorded before and after MUA. Flexion was significantly improved after MUA for both groups: early MUA from 68.4 degrees (+/-17.2 degrees ) to 101.4 degrees (+/-16.15 degrees ), P < .001; late MUA from 81.0 degrees (+/-13.3 degrees ) to 98.0 degrees (+/-18.0 degrees ), P = .001. Pain decreased significantly with early MUA from 4.92 (+/-2.25) to 3.34 (+/-2.67) and with late MUA from 4.51 (+/-2.62) to 3.44 (+/-2.78), P = .048. Extension improved only in the early MUA group from 7.15 (+/-10.1) to 2.50 (+/-4.98). Satisfaction scores were not improved. Both early and late manipulation can improve TKA pain and flexion.

Abstract
UNLABELLED Bone is an androgen-dependent tissue, but it is not clear whether the androgen action in bone depends on testosterone or on dihydrotestosterone. Patients with 5alpha-reductase 2 deficiency present normal levels of testosterone and low levels of dihydrotestosterone, providing an in vivo human model for the analysis of the effect of testosterone on bone. OBJECTIVE To analyze bone mineral density in 4 adult patients with male pseudohermaphroditism due to 5alpha-reductase 2 deficiency. RESULTS Three patients presented normal bone mineral density of the lumbar column (L1-L4) and femur neck, and the other patient presented a slight osteopenia in the lumbar column. CONCLUSION Patients with dihydrotestosterone deficiency present normal bone mineral density, suggesting that dihydrotestosterone is not the main androgen acting in bone.

Abstract
Ten male pseudohermaphrodites with 17 beta-hydroxysteroid dehydrogenase 3 (17 beta-HSD3) deficiency were evaluated in 1 clinic with an average follow-up of 10.1 years. The diagnoses were made by demonstrating low to normal serum testosterone levels, high androstenedione levels, and high ratios of serum androstenedione to testosterone in the basal state or after treatment with human chorionic gonadotropin. The molecular features of the underlying mutations were identified in all 7 families. Two additional males in the same families are believed to be affected on the basis of history obtained from family members. All of the 46,XY individuals in these families were registered at birth and raised as females (despite the presence of ambiguous genitalia in all or most), and all virilized after the time of expected puberty due to a rise in serum testosterone to or toward the normal male range. The age at diagnosis varied from 4 to 37 years. Ten individuals were studied by the same psychologist, and change of gender role (social sex) from female to male occurred in 3 subjects and in the 2 presumed affected subjects not studied. The individual with the highest serum testosterone level maintained female sexual identity, and in 2 families some of the affected males changed gender role and others did not. Thus, while androgen action plays a role in the process, additional undefined psychological, social, and/or biologic factors must be determinants of gender identity/role behavior. Management of the 7 individuals who chose to maintain female sex roles included castration, clitoroplasty, vaginal enlargement procedures when appropriate, treatment of hirsutism, cricoid cartilage reduction, and estrogen replacement. Three of the 7 are married (2 twice), 1 is involved in a long-term heterosexual relationship, 1 is engaged to be married, and the other 2 are not married and not believed to be sexually active. The 3 subjects who changed gender role behavior to male underwent hypospadias repair, and 1 was given supplemental testosterone therapy. One of these men is divorced, and the other 2 (aged 29 and 35 years) are unmarried. The diagnosis in 8 of these subjects was made after the time of expected puberty; it is unclear whether the functional and social outcomes would have been different if the diagnosis had been made and therapy begun earlier in life.

Abstract
Sixteen subjects (from 10 Brazilian families) with male pseudohermaphroditism due to steroid 5alpha-reductase 2 deficiency have been evaluated in 1 clinic. The diagnoses were made on the basis of normal plasma testosterone values, normal or low plasma dihydrotestosterone levels and high testosterone/dihydrotestosterone ratios in the basal state in postpubertal subjects or after treatment with either human chorionic gonadotropin or testosterone in prepubertal subjects. The analysis of the ratios of etiocholanolone to androsterone in urine confirmed the diagnosis in all subjects who were tested, and the molecular basis of the underlying mutations was established in 9 of the families. Fourteen of the individuals were evaluated by the same psychologist. All subjects but 1 were given a female sex assignment at birth. Three of the subjects (1 the sibling of an individual who has undergone female to male social behavior) maintain a female social sex; they have been gonadectomized and treated with exogenous estrogens. Ten of 13 subjects of postpubertal age underwent a change of social sex from female to male, had surgical correction of the hypospadias, and were treated with high-dose testosterone esters by parenteral injection and subsequently with dihydrotestosterone cream. These regimens brought serum dihydrotestosterone levels to the normal male range (or above) but resulted only in limited growth of the prostate and penis and, in some, increase in body and facial hair and enhancement of libido and sexual performance. Treatment of the prepubertal boys with testosterone and/or dihydrotestosterone resulted in a doubling of penis size.
