A quality improvement intervention to increase access to pediatric subspecialty practice

Use of Lean Six Sigma to Improve Access to Care in a Surgical Subspecialty Clinic

INTRODUCTION

At the Naval Medical Center San Diego urology clinic, patients reported waiting for greater than 1 month for an initial consult. A Lean Six Sigma approach was used to improve access to care (ATC) and decrease variation in access by improving scheduling.

METHODS

A Define-Measure-Analyze-Improve-Control approach was used. Delay to new patient visits was identified as the focus of intervention. The scheduling template was changed from a fixed stream to a modified wave based on simulation software analysis of appointment cycle times. Appointment length was adjusted based on cycle time analysis, and two rooms per clinician were used instead of one. The ratio of initial consults relative to established follow-ups and procedures was adjusted upward to better balance with the historic demand.

RESULTS

Statistically significant improvement was seen in ATC and compliance with the Defense Health Agency (DHA) standard that new consults be seen within 28 days. Average days for a new consult to be seen were reduced by 7.2 days in the pediatric urology clinic (P < 0.0001) and 6.4 days in the adult urology clinic (P < 0.0001). Compliance with the Defense Health Agency 28-day ATC standard increased from a baseline of 69.2% to 88.9% and 61.7% to 84.4%, respectively, in the pediatric and adult clinics (P < 0.001 for both). Patient satisfaction was maintained at or above the goal threshold throughout the project.

CONCLUSIONS

An Lean Six Sigma model was used to improve timeliness of care for our patients, improving the overall quality of their healthcare experience. Simulation software can be used to model the clinic throughput and test alternative scheduling templates. ATC was significantly improved and patient satisfaction was maintained at or above goal thresholds.

Paediatric bladder dysfunction: A single centre experience of public hospital wait times

AIM

Paediatric bladder dysfunction, including daytime urinary incontinence and enuresis, is a common and distressing condition. Unfortunately, children with these symptoms are often on waitlists for several months. This treatment delay may significantly impact upon the child and family unit. This study aimed to quantify waiting times for children who had attended hospital outpatient clinics for symptoms of wetting.

METHODS

A retrospective review was undertaken for patients who had been referred to The Royal Children's Hospital, Melbourne outpatient clinics for symptoms of wetting (with/without bowel symptoms). Data regarding the referral and triage pathway, up to the time of the first clinic appointment, were collected. These data were compared to a previous audit conducted in the same setting.

RESULTS

A total of 101 clinic attendances were included in this study. The overall waiting time, from receipt of referral to the patient's first clinic attendance, was a median of 181 days (n = 94 valid responses; range 7-695). Wait times for patients with isolated symptoms of wetting were similar to patients with mixed bowel and bladder dysfunction (187 and 171.5 days, respectively). Most patients were triaged to the continence clinic (n = 68), whilst smaller proportions of patients were seen in the encopresis (n = 14), urology (n = 13), general medicine (n = 2), gastroenterology (n = 1) and nurse-led enuresis clinic (n = 3).

CONCLUSIONS

The waiting times for patients with wetting generally exceeded 5 months. Alternative pathways for triage need to be explored to manage demand and improve wait times.

Access to specialty healthcare in urban versus rural US populations: a systematic literature review

Background

Access to healthcare is a poorly defined construct, with insufficient understanding of differences in facilitators and barriers between US urban versus rural specialty care. We summarize recent literature and expand upon a prior conceptual access framework, adapted here specifically to urban and rural specialty care.

Methods

A systematic review was conducted of literature within the CINAHL, Medline, PubMed, PsycInfo, and ProQuest Social Sciences databases published between January 2013 and August 2018. Search terms targeted peer-reviewed academic publications pertinent to access to US urban or rural specialty healthcare. Exclusion criteria produced 67 articles. Findings were organized into an existing ten-dimension care access conceptual framework where possible, with additional topics grouped thematically into supplemental dimensions.

Results

Despite geographic and demographic differences, many access facilitators and barriers were common to both populations; only three dimensions did not contain literature addressing both urban and rural populations. The most commonly represented dimensions were availability and accommodation, appropriateness, and ability to perceive. Four new identified dimensions were: government and insurance policy, health organization and operations influence, stigma, and primary care and specialist influence.

Conclusions

While findings generally align with a preexisting framework, they also suggest several additional themes important to urban versus rural specialty care access.

Pediatric Type 1 Diabetes: Reducing Admission Rates for Diabetes Ketoacidosis

Background:

Diabetes ketoacidosis (DKA) is a life-threatening complication of type 1 diabetes mellitus (T1DM). Reducing DKA admissions in children with T1DM requires a coordinated, comprehensive management plan. We aimed to decrease DKA admissions, 30-day readmissions, and length of stay (LOS) for DKA admissions.

Methods:

A multipronged intervention was designed in 2011 to reach all patients: (1) increase insulin pump use and basal-bolus regimen versus sliding scales, (2) transform educational program, (3) increased access to medical providers, and (4) support for patients and families. A before-after study was conducted comparing performance outcomes in years 2007-2010 (preintervention) to 2012-2014 (postintervention) using administrative data and Wilcoxon rank sum and Fischer exact tests.

Results:

DKA admissions decreased by 44% postintervention (16.7 vs 9.3 per 100 followed patient-years; P = .006), unique patient 30-day readmissions decreased from 20% to 5% postintervention (P = .001), and median LOS significantly decreased postintervention (P < .0001). Although not an original goal of the study, median hemoglobin A1C of a subset of the population transitioned from sliding scale decreased, 10.3% to 8.9% (P < .02).

Conclusions:

When clinical and widespread program interventions were used, significant reductions in DKA hospitalizations, 30-day readmissions, and LOS occurred for pediatric T1DM. Continuous performance improvement efforts are needed for improving DKA outcomes.

Effect of a Referral-Only Policy on Wait Time for Outpatient Pediatric Dermatology Appointments

Decreasing wait time for pediatric dermatology appointments is important to patients. We retrospectively examined the effect of a referral-only policy on patient wait time for an initial appointment in an academic pediatric dermatology clinic and found a statistically significant decrease in wait time after the policy was instituted.

The Current State of Pediatric Sports Medicine: A Workforce Analysis

OBJECTIVE

Pediatric sports medicine is an evolving pediatric subspecialty. No workforce data currently exists describing the current state of pediatric sports medicine. The goal of this survey is to contribute information to the practicing pediatric sports medicine specialist, employers and other stakeholders regarding the current state of pediatric sports medicine.

METHODS

The Workforce Survey was conducted by the American Academy of Pediatrics (AAP) Division of Workforce and Medical Education Policy (WMEP) and included a 44-item standard questionnaire online addressing training, clinical practice and demographic characteristics as well as the 24-item AAP Council on Sports Medicine and Fitness (COSMF) questionnaire. Descriptive statistics were used to summarize all survey responses. Bivariate relationships were tested for statistical significance using Chi square.

RESULTS

145 surveys were returned, which represented a 52.7% response rate for eligible COSMF members and board certified non-council responders. The most common site of employment among respondents was university-based clinics. The respondents board certified in sports medicine were significantly more likely to perform fracture management, casting and splinting, neuropsychological testing and injections compared to those not board certified in sports medicine. A large proportion of respondents held an academic/medical school appointment. Increases were noted in both patient volume and the complexity of the injuries the specialists were treating.

CONCLUSION

This pediatric sports medicine workforce study provides previously unappreciated insight into practice arrangements, weekly duties, procedures, number of patients seen, referral patterns, and potential future trends of the pediatric sports medicine specialist.

Improving Access to Care at Autism Treatment Centers: A System Analysis Approach

OBJECTIVE

The prevalence of autism spectrum disorder is steadily increasing and placing more demands on already overburdened diagnostic and treatment systems. A thoughtful, systematic reorganization of autism service delivery may reduce delays and better meet the growing need.

METHODS

Two clinical centers in the Autism Intervention Research Network on Physical Health, Cincinnati Children's Hospital Medical Center (CCHMC) and Nationwide Children's Hospital (NCH), undertook a year-long access improvement project to reduce delays to care by using system analysis to identify sources of delay and to target changes by using a set of defined access principles. Although both sites addressed access, they focused on slightly different targets (reducing number of patients with autism spectrum disorders waiting for follow-up appointments at NCH and reducing delay to new diagnosis at CCHMC).

RESULTS

Both sites achieved dramatic improvements in their complex, multidisciplinary systems. A 94% reduction in number of patients on the waitlist from 99 to 6 patients and a 22% reduction in median delay for a new ongoing care appointment were realized at NCH. A 94% reduction in third next available appointment for new physician visits for children 3 to 5 years old was realized at CCHMC.

CONCLUSIONS

This article demonstrates that 2 different clinical systems improved access to care for autism diagnosis and follow-up care by identifying sources of delay and using targeted changes based on a set of access change principles. With appropriate guidance and data analysis, improvements in access can be made.

Interventions to reduce waiting times for elective procedures

BACKGROUND

Long waiting times for elective healthcare procedures may cause distress among patients, may have adverse health consequences and may be perceived as inappropriate delivery and planning of health care.

OBJECTIVES

To assess the effectiveness of interventions aimed at reducing waiting times for elective care, both diagnostic and therapeutic.

SEARCH METHODS

We searched the following electronic databases: Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (1946-), EMBASE (1947-), the Cumulative Index to Nursing and Allied Health Literature (CINAHL), ABI Inform, the Canadian Research Index, the Science, Social Sciences and Humanities Citation Indexes, a series of databases via Proquest: Dissertations & Theses (including UK & Ireland), EconLit, PAIS (Public Affairs International), Political Science Collection, Nursing Collection, Sociological Abstracts, Social Services Abstracts and Worldwide Political Science Abstracts. We sought related reviews by searching the Cochrane Database of Systematic Reviews and the Database of Abstracts of Reviews of Effectiveness (DARE). We searched trial registries, as well as grey literature sites and reference lists of relevant articles.

SELECTION CRITERIA

We considered randomised controlled trials (RCTs), controlled before-after studies (CBAs) and interrupted time series (ITS) designs that met EPOC minimum criteria and evaluated the effectiveness of any intervention aimed at reducing waiting times for any type of elective procedure. We considered studies reporting one or more of the following outcomes: number or proportion of participants whose waiting times were above or below a specific time threshold, or participants' mean or median waiting times. Comparators could include any type of active intervention or standard practice.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data from, and assessed risk of bias of, each included study, using a standardised form and the EPOC 'Risk of bias' tool. They classified interventions as follows: interventions aimed at (1) rationing and/or prioritising demand, (2) expanding capacity, or (3) restructuring the intake assessment/referral process.For RCTs when available, we reported preintervention and postintervention values of outcome for intervention and control groups, and we calculated the absolute change from baseline or the effect size with 95% confidence interval (CI). We reanalysed ITS studies that had been inappropriately analysed using segmented time-series regression, and obtained estimates for regression coefficients corresponding to two standardised effect sizes: change in level and change in slope.

MAIN RESULTS

Eight studies met our inclusion criteria: three RCTs and five ITS studies involving a total of 135 general practices/primary care clinics, seven hospitals and one outpatient clinic. The studies were heterogeneous in terms of types of interventions, elective procedures and clinical conditions; this made meta-analysis unfeasible.One ITS study evaluating prioritisation of demand through a system for streamlining elective surgery services reduced the number of semi-urgent participants waiting longer than the recommended time (< 90 days) by 28 participants/mo, while no effects were found for urgent (< 30 days) versus non-urgent participants (< 365 days).Interventions aimed at restructuring the intake assessment/referral process were evaluated in seven studies. Four studies (two RCTs and two ITSs) evaluated open access, or direct booking/referral: One RCT, which showed that open access to laparoscopic sterilisation reduced waiting times, had very high attrition (87%); the other RCT showed that open access to investigative services reduced waiting times (30%) for participants with lower urinary tract syndrome (LUTS) but had no effect on waiting times for participants with microscopic haematuria. In one ITS study, same-day scheduling for paediatric health clinic appointments reduced waiting times (direct reduction of 25.2 days, and thereafter a decrease of 3.03 days per month), while another ITS study showed no effect of a direct booking system on proportions of participants receiving a colposcopy appointment within the recommended time. One RCT and one ITS showed no effect of distant consultancy (instant photography for dermatological conditions and telemedicine for ear nose throat (ENT) conditions) on waiting times; another ITS study showed no effect of a pooled waiting list on the number of participants waiting for uncomplicated spinal surgery.Overall quality of the evidence for all outcomes, assessed using the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) tool, ranged from low to very low.We found no studies evaluating interventions to increase capacity or to ration demand.

AUTHORS' CONCLUSIONS

As only a handful of low-quality studies are presently available, we cannot draw any firm conclusions about the effectiveness of the evaluated interventions in reducing waiting times. However, interventions involving the provision of more accessible services (open access or direct booking/referral) show some promise.

The estimated cost of "no-shows" in an academic pediatric neurology clinic

OBJECTIVE

Missed appointments ("no-shows") represent an important source of lost revenue for academic medical centers. The goal of this study was to examine the costs of "no-shows" at an academic pediatric neurology outpatient clinic.

METHODS

This was a retrospective cohort study of patients who missed appointments at an academic pediatric neurology outpatient clinic during 1 academic year. Revenue lost was estimated based on average reimbursement for different insurance types and visit types.

RESULTS

The yearly "no-show" rate was 26%. Yearly revenue lost from missed appointments was $257,724.57, and monthly losses ranged from $15,652.33 in October 2013 to $27,042.44 in January 2014.

CONCLUSIONS

The yearly revenue lost from missed appointments at the academic pediatric neurology clinic represents funds that could have been used to improve patient access and care. Further work is needed to develop strategies to decrease the no-show rate to decrease lost revenue and improve patient care and access.
