The Presentation, Diagnosis, and Treatment of Sexually Transmitted Infections

BACKGROUND

The reported incidence of sexually transmitted infections (STIs) in Germany is rising. For example, the number of new reported cases of syphilis rose from 3034 in 2010 to 4410 in 2012.

METHODS

This review is based on pertinent articles retrieved by a selective search in MEDLINE, and on guidelines and systematic reviews from Germany and abroad.

RESULTS

We discuss sexually transmitted infections presenting with genital, anal, perianal, or oral ulcers, urethritis, cervicitis, urethral or vaginal discharge, or genital warts. We also discuss sexually transmitted infection with HIV and the hepatitis C virus (HCV). Acquired sexually transmitted infections elevate the risk of transmission of other sexually transmitted infections; thus, patients presenting for the diagnosis or treatment of any kind of sexually transmitted infection should be evaluated for others as well. For most of these diseases, treatment of the patient's sexual partner(s) is indicated. Diagnostic nucleic acid amplification techniques are over 90% sensitive and specific and are generally the best way to detect the responsible pathogen. Factors impeding effective treatment include antibiotic resistance (an increasing problem) and the late diagnosis of HIV and HCV infections.

CONCLUSION

Sexually transmitted infections are common around the world, and any such infection increases the patient's risk of contracting other types of sexually transmitted infection. Molecular genetic diagnostic techniques should be made widely available.

[Should all dermatologists still be considered 'dermato-venereologists' in the year 2013?]

This commentary primarily focuses on the appropriateness of the predicate 'venereologist' for dermatologists in the Netherlands. If the quantity of care delivered were to be the most important factor needed for the qualification 'venereologist', the answer to the title question would undoubtedly be 'no' because more than 70% of sexually transmitted disease (STD) care is delivered in primary care centres. After the reorganisation of STD care in the Netherlands in 2006, 8 coordinating municipal STD centres were allocated for the primary care of pre-defined risk groups. By utilizing multidisciplinary guidelines, the Dutch Society of Dermatologists and Venereologists plays an important coordinating and supervisory role in current primary and in-hospital STD care.

[Guideline 'Diagnostics of small-vessel vasculitis']

The multidisciplinary guideline 'Diagnostics of small-vessel vasculitis' gives recommendations for the diagnostics of small-vessel vasculitis, which is often associated with cutaneous manifestations. The aim of this guideline is to accelerate the diagnostic process to prevent or reduce irreversible organ damage. The clinical presentation of small-vessel vasculitis is variable and often atypical. The most common general symptoms are general malaise, unexplained fever, weight loss, fatigue, loss of appetite, and night sweats. If these symptoms are accompanied by one or more organ-specific symptoms, the probability of the diagnosis 'small-vessel vasculitis' is increased. When small-vessel vasculitis is suspected a comprehensive history should be taken and a physical examination focused on internal organs, joints, skin and nervous system should be performed. With additional laboratory investigations possible organ involvement can be demonstrated and the small-vessel vasculitis can be further classified. To make a definite diagnosis histological examination of an affected organ is necessary. Because of the possible involvement of multiple organ systems, multidisciplinary collaboration is essential in the diagnostic work-up.

Excellence in sexually transmitted infection (STI) diagnostics: recognition of past successes and strategies for the future

Diagnostic advances do not generally receive the recognition given to prevention and treatment contributions, for the control and management of infectious diseases including sexually transmitted infections (STIs). In order to identify seminal diagnostic contributions over a half century (1950-2000), the Editorial Board of the WHO Sexually Transmitted Diseases Diagnostics Initiative (SDI) Publication Review or "electronic journal club" were asked to nominate their choices of peer-reviewed publications for special recognition. From 43 nominations, 13 were voted by a panel of 25 "experts" as having made the most significant contributions. The 1964 article by Thayer and Martin, which identified a selective media for gonococcal culture, was chosen unanimously by all panel members and is identified as the classic STI diagnostic article for this era.

Success of a nurse led community based genitourinary medicine clinic for young people in Liverpool: review of the first year

OBJECTIVES

To assess the outcome and workload of a community based, nurse led comprehensive sexual health and contraceptive service for clients aged less than 25.

METHODS

Review of appointment diaries and clinic records of clients who attended the Brook genitourinary medicine (GUM) clinic. The workload, case mix, and achievement of national targets in the first year of the service were compared with those for the same age group of clients attending the nearby hospital based GUM clinic. A limited client satisfaction questionnaire was carried out 8 months after the clinic opened.

RESULTS

1061/1700 (62.4%) clients (185, 17.4% male) attended booked appointments. Chlamydia trachomatis was detected in 16.1% of women and 20.5% of men at Brook (p<0.05), where 22.6% of women and 50% of men had at least one sexually transmitted infection (p<0.001). HIV testing was offered to 98.5% of clients. 60.7% of all identified contacts attended a clinic for testing and/or treatment. Client responses to a questionnaire about the service were very favourable. Only 2.3% of Brook GUM clients needed referral to a physician.

CONCLUSIONS

Nurse led community based GUM services, such as the one provided at the Merseyside Brook Centre, appeal to young people and our success should encourage others to consider similar ventures.

A national audit of gonorrhoea management

A national audit of gonorrhoea clinic policy and case management was carried out by postal survey on behalf of the National Audit Group of the British Association for Sexual Health and HIV. Ninety-three clinics out of a total of 278 (33%) and 1324 cases were included. The results showed that both the auditable outcome measures listed in the National Guideline for the Management of Gonorrhoea in Adults and the evidence-based outcome standards recently published by Low et al. were broadly being met.

[The new German educational law for medical schools: the Hamburg concept in dermatology and venereology]

Medical school graduates are required to deal with complex situations in their future work which require profound theoretical knowledge as well as many practical skills. The University of Hamburg used a new educational law (AappO 2002) as catalyst to define learning objectives relevant for practice and to guarantee a close connection between theory and practice. A newly founded curriculum committee with twelve members developed a strategy and structure for the new clinical curriculum (KliniCuM) in weekly sessions. The subject dermatology and venereology is taught in the thematic block "The Internal and External Human Being" in integrated courses with the subjects internal medicine, pathology and pharmacology. The teaching modules (introductory lectures, symptom-oriented lectures, problem-based tutorials and bedside-teaching) are practice oriented and teach diseases and skills of dermatology which are important for "general medicine". Written and practical exams take place at the end of the block. Although there is more required attendance and increased demands on students' time, dermatology has received very positive evaluation results. Students consider their gain in knowledge and skills as very high. The new curriculum in Hamburg could provide helpful orientation for other medical faculties in changing their curricula for the subject "dermatology and venereology" according to the new educational law.

Patient satisfaction with care for genital herpes: insights from a global survey

OBJECTIVE

To describe patient experiences and views regarding genital herpes management.

METHODS

Between February 2002 and January 2003, subjects with genital herpes were recruited via the International Herpes Alliance website and through banners on additional sites. Surveys were available in English, French, Spanish, Italian, and German and assessed views on access to care, diagnosis, related emotional experiences, educational resources, counselling, pharmacotherapy, and satisfaction with care.

RESULTS

2075 patient responses from 78 countries were analysed. 49% reported their diagnosis was by culture (or other direct detection) and 9% by antibody test, while 34% reported they had been diagnosed by examination alone. 65% used a prescription antiviral therapy, 18% a topical antiviral therapy, and 17% an alternative therapy. Of 901 subjects who reported on frequency of antiviral use, only 30% reported a frequency consistent with a suppressive regimen while 59% of respondents said they would be likely to take daily therapy if it reduced the frequency of outbreaks. Patient satisfaction with management of physical symptoms was independently associated with duration of initial visit >or=15 minutes (adjusted odds ratio (OR) = 4.52), receiving a prescription (adj OR = 2.34) and receipt of a brochure/fact sheet (adj OR = 2.14). Satisfaction with attention to emotional issues also correlated with the first two of these factors.

CONCLUSIONS

Genital herpes management may be improved by including the use of confirmatory laboratory testing, employing a full range of antiviral therapy options, providing educational materials, and committing more time to counselling at the initial visit.

Diagnosis of genital chlamydia in primary care: an explanation of reasons for variation in chlamydia testing

OBJECTIVES

To explore the reasons for the 40-fold variation in diagnostic testing for genital Chlamydia trachomatis by general practices.

METHODS

A qualitative study with focus groups. We randomly selected urban and rural high and low testing practices served by Bristol, Hereford, and Gloucester microbiology laboratories. Open questions were asked about the investigation of C trachomatis in men and women in different clinical contexts.

RESULTS

The high and low testing practices did not differ in their age/sex make-up or by deprivation indices. There were major differences between high and low chlamydia testing practices. Low testing practices knew very little about the epidemiology and presentation of genital chlamydia infection and did not consider it in their differential diagnosis of genitourinary symptoms until patients had consulted several times. Low testers were less aware that chlamydia was usually asymptomatic, thought it was an inner city problem, and had poor knowledge of how to take diagnostic specimens. High testing practices either had a general practitioner with an interest in sexual health or a practice nurse who had completed specialist training in family planning. High testing practices were more cognizant of the symptoms and signs of chlamydia and always considered it in their differential diagnosis of genitourinary symptoms, including patients attending family planning clinics.

CONCLUSIONS

Any programme to increase chlamydia testing in primary care must be accompanied by an education and awareness programme especially targeted at low testing practices. This will need to include information about the benefits of testing and who, when, and how to test.

Developing national outcome standards for the management of gonorrhoea and genital chlamydia in genitourinary medicine clinics

BACKGROUND

Measuring clinical performance within a framework of clinical governance is increasingly important for monitoring improvements in patient care. Standards for quality indicators must, however, be achievable and evidence based. We describe an approach to the development of national standards for measuring outcomes of care for gonorrhoea and genital chlamydia in genitourinary medicine clinics.

METHODS

Two standards for each infection, one reflecting quality of case management and one reflecting partner management were chosen by consensus. A systematic review of published and unpublished UK studies about gonorrhoea and chlamydia management was carried out and weighted averages calculated for each parameter, stratified by location. Genitourinary medicine practitioners around the country were also asked for their opinion about desirable values for each standard and the results compared. Variability in performance between centres was examined using Shewhart's control charts.

RESULTS

We identified 17 reports about gonorrhoea outcomes and 14 about chlamydia. There was marked heterogeneity in results according to geographical location and different standards were set for clinics in and out of London. Opinions from practitioners suggested much higher standards than the values obtained from the systematic review. There was evidence for special cause variation related to management of gonorrhoea and chlamydia in London clinics.

CONCLUSIONS

Standards set using expert opinion are unrealistic when compared to evidence of what is achievable. Evidence based methods should therefore be used to derive outcome standards for case management gonorrhoea and chlamydia. The control chart method identified clinics where investigation to find reasons for special cause variation in performance should be undertaken to change practice.

Quality of sexually transmitted infections services for female sex workers in Abidjan, Côte d'Ivoire

OBJECTIVES

To assess the quality of sexually transmitted infections (STI) care in health care facilities in Abidjan attended by female sex workers.

METHODS

A cross-sectional study was conducted in June 2000 in the 29 health care facilities and 10 pharmacies, which were reported as points of first encounter for STI care by female sex workers in a previous study on health seeking behaviour. Evaluation components included: (1) checklists of equipment and STI drugs in the facilities; (2) interviews with health care providers and pharmacists; (3) direct observation of the provider/client interaction; (4) exit interviews with women attending with STI or genital problems.

RESULTS

Private health care facilities were more expensive, had fewer clients, and had less equipment and medical staff than public facilities, with the exception of the special female sex worker clinic. A total of 60 health care providers and 29 pharmacists were interviewed. There was no difference in their scoring on syndromic approach case studies, with the exception of the nurse assistants, who scored less. Overall scores for correct treatment were lowest for the pharmacists. We observed 513 provider-client interactions, of which 161 related to STIs or genital problems in women. Questions about recent sexual contacts were asked in only 20% and preventive messages were given in only 9% of the cases with STI/genital problems. Of 161 clients interviewed, 44% complained about a long waiting time, and 39% thought the health care provider had adequately explained the problem to them.

CONCLUSIONS

The opportunity for improvement of STI case management in health care facilities in Abidjan where female sex workers go for STI care is enormous. Public and private health care facilities should be made more accessible for sex workers, and their services should be upgraded to better respond to the sexual health needs of high risk women.

Variation in clinical practice in genitourinary medicine clinics in the United Kingdom

OBJECTIVES

This study was conducted to examine the variation in clinical practice in genitourinary medicine clinics in the United Kingdom in early 2002.

METHODS

Questionnaires were sent to all 234 consultants in charge of genitourinary medicine clinics in the United Kingdom in March-May 2002. The questions concerned clinical practice in respect of asymptomatic patients presenting for an infection screen, and practice in respect of some specific sexually transmitted and other genitourinary infections.

RESULTS

The test for infection least likely to be offered to heterosexuals is an HIV test (71% and 70% of clinics routinely offer this to male and female heterosexuals respectively). The practice of permitting "low risk" patients to telephone for their HIV results now extends to 24% of clinics. 34% of clinics do not require patients with non-specific urethritis to attend for follow up. 41% of clinics routinely ask patients treated for Chlamydia trachomatis to return for a follow up chlamydia detection test. 25% of clinics routinely offer two tests of cure to all patients with gonorrhoea. 6% of clinics do not routinely offer syphilis serology to heterosexuals. Other significant variations in clinical practice were documented.

CONCLUSIONS

Overall, our findings indicate the need for further evidence to guide clinical practice and a wider knowledge and debate of national guidelines.

National guideline for the management of suspected sexually transmitted infections in children and young people

The Children Act 1989 defines a child as "a person who has not yet reached 18 years of age." In England, Wales, and Scotland the present age of consent for heterosexual and homosexual sex is 16 years and in Northern Ireland it is 17 years. The proportion of young people who report heterosexual intercourse before the age of 16 years increased in the 1990s compared with the previous decade.

Comparing doctor- and nurse-led care in a sexual health clinic: patient satisfaction questionnaire

BACKGROUND

A new model of comprehensive care nurse-led clinics has enabled experienced genitourinary medicine nurses to co-ordinate the first-line, comprehensive care of female patients presenting with sexually transmitted infections and other sexual health conditions and issues.

AIM

This paper describes the development of a patient satisfaction questionnaire to compare the satisfaction of women attending nurse-led or doctor-led clinics at a central London genitourinary medicine clinic.

METHODS

A previously validated questionnaire was adapted using the findings of qualitative interviews exploring patient expectations of the service. The draft questionnaire was tested for internal consistency, sub-scale homogeneity, construct validity and stability. The final version consisted of a 34 item, five-point Likert scale, which was found to be both reliable (Cronbach's alpha 0.91) and stable (test-retest 0.95). There was some evidence of construct validity. The questionnaire was then distributed to a convenience sample of 132 women attending a nurse-led clinic and 150 seen at a doctor-led clinic.

RESULTS

There was a 90% response rate. The median total satisfaction scores, out of a total of five, were 4.47 and 4.30 for the nurse-led and doctor-led groups, respectively (P = 0.05). Significantly higher scores on the sub-scales measuring quality and competence of technical care (P < 0.001), provision of information (P = 0.01) and overall satisfaction (P = 0.01) were seen for the nurse-led group. No significant differences were found in the sub-scales measuring service attributes and specific attributes of interpersonal relationships.

CONCLUSION

The rigorous development, piloting and testing phases of this satisfaction questionnaire led to reliable and valid results. This study demonstrated that nurse-led clinics within this service are an acceptable alternative to the existing doctor-led clinics.

"That sort of place...where filthy men go...": a qualitative study of women's perceptions of genitourinary medicine services

BACKGROUND

A stigma is a pejorative social label. Stigmatisation is a process by which individuals are made to experience isolation and reduced opportunities in life. Some diseases are particularly associated with stigmatising attitudes; this applies particularly to sexually transmitted infections. Although several studies report the effects of stigma, no study to date has attempted to investigate its nature, which is a prerequisite to designing health interventions.

METHODS

This qualitative, exploratory study investigated the experience of stigma among young women recently diagnosed with an STI and considered the implications of these experiences in terms of maximising access to GUM clinics.

RESULTS

Three themes were identified from interviews undertaken with women recruited in family planning and genitourinary medicine (GUM) clinics: the perception of STIs as a condition of "others," the threatening nature of the GUM clinic, and the evolution of the experience of stigma within the GUM clinic.

CONCLUSION

More open discussion and education about sexual health services and STIs should take place at a general population level; awareness of sexual health services should be raised in inclusive ways, which are seen as relevant to the needs of a wide range of individuals; medical, nursing, and counselling staff in GUM clinics should be supported in their efforts to reduce the experience of stigma. Finally, future interventions designed to improve access to sexual health services should formally assess their impact on stigma.

Access to genitourinary medicine clinics in the United Kingdom

OBJECTIVES

To assess the variability in time taken for a patient to be seen in a genitourinary (GUM) clinic in the United Kingdom having contacted that clinic by telephone and compare this with GUM physicians' expectations.

METHODS

A postal questionnaire was sent to lead GUM physicians asking when they thought patients with two specific clinical scenarios would be seen in their clinics. Following this, healthcare personnel contacted individual units posing as patients with the same clinical scenarios and asked to be seen as soon as possible.

RESULTS

202/258 (78%) lead clinicians responded to the postal questionnaire. All clinics claimed to have procedures allowing patients with acute symptoms to be assessed urgently and estimated that such patients would be seen within 48 hours of the initial telephone contact. In 243 of 311 (78%) clinic contacts, the patient was invited to attend the clinic within 48 hours. For the remaining 68 contacts (22%) the patient could not be accommodated within 48 hours and, of these, 49 could not be seen for more than 1 week.

CONCLUSIONS

No clinician estimated that patients with acute severe symptoms would be seen more than 48 hours after the initial telephone contact, but in reality, for 22% of the patient contacts this was the case. This study may well underestimate the difficulties the general public may have in accessing GUM services. We hypothesise that this situation could be ameliorated by establishing process standards and addressing issues of resource allocation.
