A prescription for improvement? An observational study to identify how general practices vary in their growth in prescribing costs

Generic medicines and generic substitution: contrasting perspectives of stakeholders in Ireland

BACKGROUND

The Health (Pricing and Supply of Medical Goods) Act 2013 passed into law in July 2013 and legislated for generic substitution in Ireland. The aim of the study was to ascertain the knowledge and perceptions of stakeholders i.e. patients, pharmacists and prescribers, of generic medicines and to generic substitution with the passing of legislation.

METHODS

Three stakeholder specific questionnaires were developed to assess knowledge of and perceptions to generic medicines and generic substitution. Purposive samples of patients, prescribers and pharmacists were analysed. Descriptive quantitative and qualitative analyses were undertaken.

RESULTS AND DISCUSSION

A total of 762 healthcare professionals and 353 patients were recruited. The study highlighted that over 84% of patients were familiar with generic medicines and are supportive of the concept of generic substitution. Approximately 74% of prescribers and 84% of pharmacists were supportive of generic substitution in most cases. The main areas of concern highlighted by the healthcare professionals that might impact on the successful implementation of the policy, were the issue of bioequivalence with generic medicines, the computer software systems used at present in general practitioner (GP) surgeries and the availability of branded generics. The findings from this study identify a high baseline rate of acceptance to generic medicines and generic substitution among patients, prescribers and pharmacists in the Irish setting. The concerns of the main stakeholders provide a valuable insight into the potential difficulties that may arise in its implementation, and the need for on-going reassurance and proactive dissemination of the impact of the generic substitution policy.

CONCLUSION

The existing positive attitude to generic medicines and generic substitution among key stakeholders in Ireland to generic substitution, combined with appropriate support and collaboration should result in the desired increase in rates of prescribing, dispensing and use of generic medicines.

Receptionist input to quality and safety in repeat prescribing in UK general practice: ethnographic case study

OBJECTIVE

To describe, explore, and compare organisational routines for repeat prescribing in general practice to identify contributors and barriers to safety and quality.

DESIGN

Ethnographic case study.

SETTING

Four urban UK general practices with diverse organisational characteristics using electronic patient records that supported semi-automation of repeat prescribing.

PARTICIPANTS

395 hours of ethnographic observation of staff (25 doctors, 16 nurses, 4 healthcare assistants, 6 managers, and 56 reception or administrative staff), and 28 documents and other artefacts relating to repeat prescribing locally and nationally.

MAIN OUTCOME MEASURES

Potential threats to patient safety and characteristics of good practice.

METHODS

Observation of how doctors, receptionists, and other administrative staff contributed to, and collaborated on, the repeat prescribing routine. Analysis included mapping prescribing routines, building a rich description of organisational practices, and drawing these together through narrative synthesis. This was informed by a sociological model of how organisational routines shape and are shaped by information and communications technologies. Results Repeat prescribing was a complex, technology-supported social practice requiring collaboration between clinical and administrative staff, with important implications for patient safety. More than half of requests for repeat prescriptions were classed as "exceptions" by receptionists (most commonly because the drug, dose, or timing differed from what was on the electronic repeat list). They managed these exceptions by making situated judgments that enabled them (sometimes but not always) to bridge the gap between the idealised assumptions about tasks, roles, and interactions that were built into the electronic patient record and formal protocols, and the actual repeat prescribing routine as it played out in practice. This work was creative and demanded both explicit and tacit knowledge. Clinicians were often unaware of this input and it did not feature in policy documents or previous research. Yet it was sometimes critical to getting the job done and contributed in subtle ways to safeguarding patients. Conclusion Receptionists and administrative staff make important "hidden" contributions to quality and safety in repeat prescribing in general practice, regarding themselves accountable to patients for these contributions. Studying technology-supported work routines that seem mundane, standardised, and automated, but which in reality require a high degree of local tailoring and judgment from frontline staff, opens up a new agenda for the study of patient safety.

Is new drug prescribing in primary care specialist induced?

BACKGROUND

Medical specialists are often seen as the first prescribers of new drugs. However, the extent to which specialists influence new drug prescribing in primary care is largely unknown.

METHODS

This study estimates the influence of medical specialists on new drug prescribing in primary care shortly after market introduction. The influence of medical specialists on prescribing of five new drugs was measured in a cohort of 103 GPs, working in 59 practices, over the period 1999 until 2003. The influence of medical specialists on new drug prescribing in primary care was assessed using three outcome measures. Firstly, the proportion of patients receiving their first prescription for a new or reference drug from a specialist. Secondly, the proportion of GPs prescribing new drugs before any specialist prescribes to their patients. Thirdly, we compared the time until the GP's first own prescribing between GPs who waited for prescriptions from specialists and those who did not.

RESULTS

The influence of specialists showed considerable differences among the new drugs studied. The proportion of patients receiving their first prescription from a specialist was greatest for the combination salmeterol/fluticasone (60.2%), and lowest for rofecoxib (23.0%). The proportion of GPs prescribing new drugs before waiting for prescriptions from medical specialists ranged from 21.1% in the case of esomeprazole to 32.9% for rofecoxib. Prescribing new drugs by specialists did not shorten the GP's own time to prescribing.

CONCLUSION

This study shows that the influence of medical specialists is clearly visible for all new drugs and often greater than for the existing older drugs, but the rapid uptake of new drugs in primary care does not seem specialist induced in all cases. GPs are responsible for a substantial amount of all early prescriptions for new drugs and for a subpopulation specialist endorsement is not a requisite to initiate in new drug prescribing. This contradicts with the idea that the diffusion of newly marketed drugs always follows a two-step model, with medical specialists as the innovators and GPs as the followers.

Mini-symposium — Public Health Observatories

An indicator is a measure used to express the behaviour of a system or part of a system. Indicators are widely used in the public sector, and there is widespread use of indicators for performance management of public health. In this paper, we define some of the terms used in relation to indicators. We outline some of the most important issues around selection and construction of indicators, and we include criteria for developing or assessing indicators. Use of inappropriate indicators can be misleading and can result in negative consequences for public health, and we point out the potential for pitfalls. Some misinterpretation of indicators could be avoided by use of better methods of presentation than the familiar league table. We use the example of a funnel plot to show a method of summarising indicator data which avoids ranking, and allows rapid identification of areas functioning outside normal limits.

Quality circles to improve prescribing patterns in primary medical care: what is their actual impact?

RATIONALE, AIMS AND OBJECTIVES

Quality circles comprise small group sessions of doctors and written feedback on their individual practice patterns. Although 50% of German primary care doctors participate in quality circles, their effectiveness has hardly been evaluated in Germany. This study determined the impact of a large-scale programme of quality circles on quality and costs of prescribing.

METHOD

A controlled before-after study was performed, in which primary care doctors were allocated to a quality circles group or a control group. Subjects were 100,000 patients in 1996 and in 1998, who had visited one of 177 doctors in the 3 month registration periods in one region in Germany. The intervention comprised a quality circles programme, comprising 11 sessions and repeated feedback on prescribing. Main outcome measures were proportion of patients who received a prescription, mean prescription costs per patient and proportion of generic prescriptions.

RESULTS

The absolute numbers of prescriptions decreased in both groups, but the mean prescription costs per patient increased. The quality circles reduced the proportion of patients who received a prescription (OR = 0.86) and the mean prescription costs per patient (B = -3.99 euro), while it increased the proportion of generic drugs (OR = 1.10). The intervention had intended effects on four of the 15 secondary indicators.

CONCLUSIONS

Large-scale application of quality circles had intended effects on prescribing decisions in primary care in Germany. The effects found in this study may reflect better what improvements can be achieved than randomized trials of similar interventions.

Morbidity, deprivation and drug prescribing: factors affecting variations in prescribing between doctors' practices

Analyses are reported of the prescribing quality and behaviour of 131 doctors' practices in a South Wales health authority during the first quarter of 1997. Prescribing of specific groups of drugs are examined, namely antidepressants; bronchodilators and inhaled corticosteroids for treating asthma; and oral antidiabetics and insulin for diabetes. It is hypothesised that the volumes and costs of prescriptions are determined by the characteristics of both doctors/practices (number and age of doctors; training and fundholding status of practices; single-handed practices and doctors per patient) and their patients (age; gender; ethnicity; deprivation). The health authority's population is characterised by substantial inequalities in wealth and health. Statistical analyses reveal the consistent influence of deprivation on prescribing costs and volumes, with the exception of items of insulin. Supply factors exert more selective influences. Thus, the number of doctors per practice and per patient has a positive influence on antidepressant prescribing; fundholding status is associated with lower costs for bronchodilator prescribing; and older doctors tend to prescribe more bronchodilators and oral antidiabetics. Residuals from the statistical analyses suggest further systematic influences, notably advice from hospital consultants, as well as more localised and less consistent effects.

Physician and practice characteristics associated with the early utilization of new prescription drugs

BACKGROUND

Prescription of new drugs contributes to substantial increases in annual drug expenditures. A small proportion of physicians appear to be early users of new prescription drugs and little is known about their characteristics.

OBJECTIVE

To estimate the initial utilization rate of new prescription drugs among physicians, and the physician and practice characteristics associated with early use.

DESIGN

Cumulative prospective assessment over a 5 year period (1989-1994) of new drug utilization rates in a randomly selected cohort of Quebec physicians.

PARTICIPANTS

1661 physicians and 669,867 elderly patients.

OUTCOME

Prescribing rate of 20 new drugs, in 6 therapeutic categories, to elderly patients in the first 6 months after inclusion in the Quebec formulary.

RESULTS

The 20 new drugs were prescribed by 1.3-22.3% of physicians, and there was an 8 to 17-fold difference in new drug utilization rates among prescribers. Characteristics associated with higher rates of utilization differed for general practitioners and specialists. Male general practitioners, and physicians graduating from the most recently established medical school in the province, had higher rates of new drug utilization, whereas recent graduation was only associated with higher utilization rates among specialists. Practice volume was associated with higher rates of utilization among GPs. For both GPs and specialists, having a high proportion of elderly in one's practice and a rural or remote practice location was associated with lower utilization rates.

CONCLUSIONS

Physician sex, specialty, medical school, years since graduation, practice location, volume, and relative proportion of elderly in the physician's practice influence the utilization of new drugs.

A qualitative study to explore influences on general practitioners' decisions to prescribe new drugs

BACKGROUND

Ensuring appropriate prescribing is an important challenge for the health service, and the need for research that takes account of the reasons behind individual general practitioners' (GPs) prescribing decisions has been highlighted.

AIM

To explore differences among GPs in their decisions to prescribe new drugs.

DESIGN OF STUDY

Qualitative approach, using in-depth semistructured interviews.

SETTING

Northern and Yorkshire Health Authority Region.

METHOD

Participants were identified from a random sample of 520 GPs in a quantitative study of patterns of uptake of eight recently introduced drugs. Purposeful sampling ensured inclusion of GPs prescribing any of the eight drugs and working in a range of practice settings. Fifty-six GPs were interviewed, using a topic guide. Interviews were recorded on audiotape. Transcribed text was methodically coded and data were analysed by constantly comparing emerging themes.

RESULTS

Both low and high prescribers shared a view of themselves as conservative in their prescribing behaviour. Low prescribers appeared to conform more strongly to group norms and identified a consensus among practice partners in prescribing and cost-consciousness. Conformism to group norms was represented by a commitment to practice formularies. High prescribers more often expressed themselves to be indifferent to drug costs and a shared practice ethos.

CONCLUSIONS

A shift in the attitudes of some GPs is required before cost-effectiveness is routinely incorporated in drug prescribing. The promotion of rational prescribing is likely to be more successful if efforts are focused on GPs' appreciation of cost issues and attitudes towards shared decision-making and responsibility.

The impact of a general practice group intervention on prescribing costs and patterns

BACKGROUND

The formation of primary care groups (PCGs) and trusts (PCTs) has shifted the emphasis from individual practice initiatives to group-based efforts to control rising prescribing costs. However, there is a paucity of literature describing such group initiatives. We report the results of a multilevel group initiative, involving input from a pharmaceutical adviser, practice comparison feedback, and peer review meetings.

AIM

To determine the impact of a prescribing initiative on the prescribing patterns of a group of general practices.

DESIGN OF STUDY

A comparative study with non-matched controls.

SETTING

Nine semi-rural/rural practices forming a commissioning group pilot, later a PCG, in Southern Derbyshire with nine practices as controls.

METHOD

Practice data were collated for overall prescribing and for therapeutic categories, between the years 1997/1998 and 1998/1999 and analysed statistically. Prescribing expenditure trends were also collated.

RESULTS

Although both groups came well within their prescribing budgets, in the study group this was for the first time in five years. Their rate of increase in expenditure slowed significantly following the initiative compared with that of the comparison group, which continued to rise (median practice net ingredient cost/patient unit (nic/PU) increase: Pound Sterling0.69 and Pound Sterling3.80 respectively; P = 0.03). The study group's nic/PU dropped below, and stayed below, that of the comparison group one month after the start of the initiative. For most therapeutic categories the study group had lower increases in costs and higher increases in percentage of generic items than the comparison group. Quality markers were unaffected.

CONCLUSION

We suggest that practices with diverse prescribing patterns can work together effectively within a PCT locality to control prescribing costs.
