PURPOSE

Although public health informatics (PHI) was defined in 1995, both then and still now it is an "emerging" profession. An emergent profession lacks a base of "technical specialized knowledge." Therefore, we analyzed MEDLINE bibliographic citation records of the PHI literature to determine if a base of technical, specialized PHI literature exists, which could lead to the conclusion that PHI has emerged from its embryonic state.

METHOD

A MEDLINE search for PHI literature published from 1980-2006 returned 16,942 records. Record screening by two subject matter experts netted 2493 PHI records that were analyzed by the intervals of previous PHI CBMs 96-4 and 2001-2 for 1980-1995 (I(1980)) and 1996-2000 (I(1996)), respectively, and a new, third interval of 2001-2006 (I(2001)).

RESULTS

The distribution of records was 676 (I(1980)), 839 (I(1996)) and 978 (I(2001)). Annual publication rates were 42 (I(1980)), 168 (I(1996)), and 163 (I(2001)). Cumulative publications were accelerating. A subset of 19 (2.5%) journals accounted for 730 (29.3%) of the records. The journal subset average (+/-SD) annual publication rates of 0.7+/-0.6 (I(1980)), 2.9+/-1.9 (I(1996)), and 3.1+/-2.7 (I(2001)) were different, F(3, 64)=7.12, p<.05. Only I(1980) was different (p<.05) from I(1996) or I(2001). Average (+/-SE) annual rate of increase for all journals (8.4+/-0.8 publications per year) was different from the subset of 19 (2.7+/-0.3), t(36)=5.74, p<.05. MeSH first time-to-indexing narrowed from 7.3 (+/-4.3) years to the year (0.5+/-0.8) the term was introduced, t(30)=7.03, p<.05.

CONCLUSION

A core set of journals, the proliferation of PHI articles in varied and numerous journals, and rapid uptake of MeSH suggest PHI is acquiring professional authority and now should not be tagged as an "emerging" profession.

目的

尽管公共卫生信息学（PHI）在1995年就已被定义，但在当时以及现在它都是一个“新兴”专业。一个新兴专业缺乏“技术专业知识”基础。因此，我们分析了PHI文献的MEDLINE书目引用记录，以确定是否存在技术专业的PHI文献基础，这可能会得出PHI已从其萌芽状态发展起来的结论。

方法

对1980 - 2006年发表的PHI文献进行MEDLINE检索，返回了16942条记录。两位主题专家对记录进行筛选，得到2493条PHI记录，分别按之前的PHI CBMs 96 - 4和2001 - 2的时间间隔对1980 - 1995年（I(1980)）和1996 - 2000年（I(1996)）以及一个新的2001 - 2006年的第三个时间间隔（I(2001)）进行分析。

结果

记录分布为676条（I(1980)）、839条（I(1996)）和978条（I(2001)）。年发表率分别为42条（I(1980)）、168条（I(1996)）和163条（I(2001)）。累积出版物数量在加速增长。19种（2.5%）期刊的子集占记录的730条（29.3%）。该期刊子集的平均（±标准差）年发表率分别为0.7±0.6（I(1980)）、2.9±1.9（I(1996)）和3.1±2.7（I(2001)），存在差异，F(3, 64)=7.12，p<0.05。只有I(1980)与I(1996)或I(2001)不同（p<0.05）。所有期刊的平均（±标准误）年增长率（每年8.4±0.8篇出版物）与19种期刊的子集（2.7±0.3）不同，t(36)=5.74，p<0.05。医学主题词（MeSH）首次编入索引的时间从7.3（±4.3）年缩短到该术语引入当年的（0.5±0.8）年，t(30)=
